Environmental standards are compatible with environmental laws and play an important role in national environmental management. From the development history of environmental standards, it has been developed in conjunction with environmental law. Initially, in areas where industry is intensive, people are concentrated, and pollution is severe, the emission standards for major pollutants are specified in a separate regulation that establishes pollution control. After the 1950s, the development of environmental pollution in industrialized countries became a national public hazard. At the same time as strengthening environmental legislation, it began to develop a national monthly standard, and gradually developed into a multi-level, multi-form, multi-purpose complete The environmental standards system has become an indispensable part of the environmental law system. Environmental standards play the following roles in national environmental management. 1. Environmental standards are the main basis for the formulation of national environmental plans and plans. When developing environmental plans and plans, countries must have a clear environmental goal and a series of environmental indicators. It needs to control the environmental quality to an appropriate level based on the comprehensive consideration of the country's economic and technological level, that is, to meet the requirements of the slope standard. Environmental standards make it the primary basis for developing environmental plans and plans. 2. Environment You must be the basis and basis for the formulation and implementation of environmental law. In various single-line environmental regulations, it is usually only required that emissions of pollutants must meet emission standards, and what kind of legal liabilities should be borne by environmental polluters. What is the cause of pollution? What are the specific criteria for discharging pollutants? It needs to be determined by setting environmental standards. The implementation of environmental law, especially the determination of the boundaries between lawfulness and illegality, and the determination of specific legal responsibilities, are often based on environmental standards. Therefore, environmental standards are an important basis for the formulation and implementation of environmental laws. 3. Environmental standards are the technical basis of national environmental management. Environmental management, including environmental planning and policy formulation, environmental legislation, environmental monitoring and evaluation, and daily environmental supervision and management, all need to follow and comply with environmental standards and environmental standards. Improve the level and efficiency of a country's scientific environment management.
